New solutions for pipe penetrations help prevent fire from spreading to other fire compartments for up to two hours

Tested according to the European standard EN 1366-3, the new fire protection solution is a maintenance free, sustainable solution for combustible and non-combustible pipes. The solution is based on the Paroc Hvac Section AluCoat T, which works as a vapor barrier and eliminates the risk of damage caused by condensation as well as preventing fire from spreading to other fire compartments for up to 120 minutes.

Why Paroc fire protection solutions for pipe penetrations:

Safe solution

PAROC fire protection solutions for pipe penetrations is fire resistant up to 120 minutes and are based on one non-combustible thermal insulation product: PAROC Hvac Section AluCoat T. The product has an AluCoat facing which works as a vapour barrier and eliminates the risk of damage caused by condensation.

Multiple application

PAROC fire protection solutions for pipe penetrations cover a large number of different pipe types: conventional copper and iron pipes, and also steel, stainless steel, cast iron, plastic and composite pipes of different thicknesses. The solution can be used in rigid decks and walls, such as concrete or aerated concrete. It is also tested and classified for fire rated flexible walls e.g. gypsum boards and studs. Pipes used for drinking water, heating water, comfort cooling and unventilated sewage pipes are all included in the solution.

Maintenance-free, long-term solution

PAROC stone wool is Euroclass A1 classified, which is the highest class of building material fire performance. Using insulation solutions made with PAROC stone wool products therefore means long-term, maintenance-free fire protection that does not deteriorate with time, but keeps its insulating and fire protection properties.

Tested according harmonised European standard EN 1366-3

EN 1366-3 is a harmonized European standard for fire resistance tests for penetration seals. The test method covers seals for pipes penetrating a fire-classified wall, e.g. an EI 90 wall. The sealing must prevent the fire from spreading for at least this time and have the same classification as the wall.
